We understand your concern and we commend you for bringing this sensitive matter to us in the name of Jesus Christ. It's important to address this issue with love, understanding, and a firm biblical foundation. The Bible gives no approval for masturbation and it is not free from lust or selfishness. Sex is a wonderful gift from God, designed to be enjoyed within the bounds of marriage between a man and a woman and God.
Masturbation is often a byproduct of lustful thoughts and sexual immorality, which are addressed in the Bible. "But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart." Matthew 5:28 WEB. And we are called not to have any sexual immorality among us, "that each one of you know how to possess himself of his own body in sanctification and honor, not in the passion of lust, even as the Gentiles who don’t know God" 1 Thessalonians 4:4-5, WEB.
Let's pray together for your husband in the name of Jesus Christ:
"Father in heaven, we come before You in the mighty name of Jesus Christ, lifting up this beloved husband. We pray that You would deliver him from any struggle with masturbation and any underlying lust or sinful desires. Purify his heart and mind, and help him to take every thought captive to obey Christ.
We pray in Jesus's name for the forgiveness, cleansing, and healing of past sins in this area. Help him to walk in the Spirit, as we know walking in the Spirit will not fulfill the lust of the flesh according to Galatians 5:16. Help him to walk in the Spirit, putting to death the deeds of the body which lives because of the Spirit of Christ Jesus according Romans 8:13.
Strengthen his resolve to live a life pleasing to You, and help him to be a godly husband and an example to all believers in faith, purity, and love. We pray in faith and we believe in the power of God, our Father for this prayer to be answered. Surround him with Your love, and fill him so full of your Spirit and knowledge of the word of God that there is no room for lustful thoughts and masturbation. Shock us all and glorify your name and Jesus Christ in his life
In the name of our Lord Jesus Christ, we pray, trusting in His mighty power to save, heal, and transform. Amen."
Encourage your husband to engage in activities that honor God and strengthen his relationship with Jesus Christ. He should be in God's word daily. Remind him of the words of the Apostle Paul, "Finally, brothers, whatever things are true, whatever things are honorable, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report; if there is any virtue, and if there is any praise, think about these things." Philippians 4:8, WEB.
We also encourage you to support your husband with love, understanding, and patience. Pray together, and encourage each other to live lives that honor God and your marriage. Be open and honest in your communication, and seek God's will together in Jesus's name.
